Product detail

Alumina, also known as Aluminum Oxide or Al2O3, is a hard-wearing advanced technical ceramic material frequently used in a wide variety of industrial, medical, and electronic applications. Alumina ceramic sheet made of 96% alumina ceramic has excellent properties of high temperature resistance, good thermal conductivity,  good electrical insulation, low dielectric loss, high strength and hardness, low density etc. The excellent properties make alumina sheets have a wide applications in electronic applications like hybrid integrated circuits, LED ceramic cooling bases, power modules, semiconductor devices, etc.

Mascera offers high quality alumina ceramic sheet in custom design and dimensions, we are able to produce ceramic sheets in different technologies according to the required thickness, flatness and surface finish.  For ceramic sheet with a thickness less than 1.5mm, we make it by tap casting and laser machining (laser scribing, laser cutting, laser drilling); for ceramic sheet with a thickness higher than 1.5mm, we make it by dry pressing and make precision machining by a machining lathe. Mascera can cooperate not only for bulk orders, but also prototypes or small volume orders. 

Main Properties of Alumina Ceramic Sheet

  • High mechanical strength and hardness

  • Good electrical insulation

  • Low dielectric constant and dielectric loss

  • High thermal conductivity

  • Excellent corrosion resistance

  • Non-toxic

  • Low weight
